Real Store for 12v LED Lights?

You have to look at the lumens. Watts doesn't work when comparing different types of light sources (LEDs to incandescent bulbs or fluorescent). FWIW, 250 lumens is about the same as 20 watt household type bulb.

This is true but to order LED's on ebay many sellers make you choose how many watts you want.
